To all whom it may concern.-

Be it known that I, ORVILLE M. MORSE, of Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Dust-Collectors, (for which patents have been granted in the following countries: England, July 20, 1886, No. 4,423; Germany, July 25, 1886, No. 89,219; France, July 27, 1886, No. 177,638; Belgium, July 27,

To 1886, No. 74,005; Canada, September 3, 1886,

7 No. 24,854; Italy, December 15, 1887, No. 22,525, and Austria-Hungary, April 11, 1888, No. 49,960,) of which the following isa specificat-ion.

This invention relates to a dust-collector which contains a separating case or chamber into which the dust-laden air enters tangentially, and in which the air assumes a whirling or gyrating motion, by which the dust is driven to the periphery of the whirling body of air and against the inner surface of the separating-case. A dust-collector of this kind is described and claimed in another application for patent filed by me March 31, 1886, Serial No. 197,307.

The object of the present invention is to compel all of the air and solid matter which enter the separating-chamber to take part in the whirling motion for a sufficient length of 0 time to free the air from the solid matter before the air is permitted to escape from the separating-chamber.

My invention consists of the improvements, which will be hereinafter fully described, and

5 pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved dustcollector. Fig. 2 is a top plan View thereof. Fig. 3 is a horizontal section in line as as, Fig.

c 1, the tubular guard being omitted. Fig. 4 is a longitudinal vertical section through the dust-discharge passage at the large end of the separating-chamber.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the machine, and B the conical or tapering sepa= rating-chamber supported in the same.

C represents the spout through which the dust-laden air enters the large end of the chamber B in a tangential direction.

(1 represents the discharge-opening for the fine or light dust, formed at the apex or small end of the tapering chamber B.

E represents the cover or head which closes 5 5 the large end of the chamber B, and which is provided with a large central opening, 6, through which the purified air escapes from the machine.

f is a tubular guard secured to the head E in the opening 6, and depending, preferably, below the lower edge of the opening 0 of the air-inlet spout O, as represented in Fig. 1.

g represents the discharge-passage for the large or heavy dust or material, arranged at the periphery of the large end of the tapering separatingchamber. This passage is preferably formed by a recess cut into the under side of the head E, as represented in Figs.

1 and 4, and extending outwardly from the interior of the chamber B to the outer side of the head, as represented by dotted lines in Fig.2. The outer end of the passage 9 connects with a descending spout, G, by which the heavy material is conducted to a suitable receptacle.

The dust-laden air enters the tapering chamber in a tangential direction and assumes a whirling or gyrating motion in the same, forming a vortex in which the dust-particles are quickly driven to the periphery of the whirling body of air, thereby freeing the inner portion of the whirling body of air from dust. The fine and light dust-particles move in helical lines of gradually-decreasing radius toward the small end of the tapering chamberB and escape finally through the opening (1. The large and heavy particles move in helical lines of gradually-increasing radius toward the large end of the tapering chamber B and escape finally through the passage g. The air which has been free from dust escapes through the opening e, which is protected by the depending tubular guard f. The latter prevents dust-particles which have just entered the chamber B from the spout C from passing directly into the outgoing current of purified air and escaping with the same.

H represents a wiper or cleaner arranged in the small portion of the tapering chamber B, so as to rest against the inner side thereof. The chamber B is provided at its lower end with a bracket-bearing, 1, depending below the opening (1, and provided in the axis of the chamber B with a step-bearing, in which the lower end of the wiper H is journaled, so as to be capable of turning freely in its inclined position when resting against the side of the chamber B. The wiper H is so light that it is rapidly rotated by the air-current, and its upper end is provided with a head, h, of leather or other soft material, to prevent noise. The wiper H extends only through the narrow portion of the chamber B, as the large portion of the same is kept clearbythc air-current when working upon ordinary material. WVhen the material contained in the air is very adhesive, a wiper extending to the large end of the chamber B may be employed. The fine dust escaping from the opening (.1 passes into a conveyer-trough, J, and the heavy dust escaping through the spout G passes into a 0011- veyer-trougli, K.

I do not wish to claim in this application the construction of the separating-chamber itself, which is claimed in said prior application No. 197,307; neither do I wish to claim herein the dustdischarge at the large end of the separating-chamber, nor the cleaner, as these features are claimed in Letters Patent Nos. 370,020 and 370,021, dated SeptemberlS, 1887, granted upon subdivisions of this application filed by me August 20 and 22, 1887, respectively, Serial Nos. 247,430 and 247,540.

I claim as my invention 1. A dust-collector consisting of a separating-chamber having an imperforate periph eral wall in which the whirling body of air forms a vortex, and in which the air moves from the periphery toward the axis of the vortex as it becomes freed from the solid matter, said chamber having at one end a dischargeaperture for the purified air opening into the atmosphere, and provided with a tubular guard projecting into the separating-chamber, at its opposite end a discharge opening for the separated dust, and a tangential inlet for the dustladen air, substantially as set forth. 2. A dust-collector consisting of a tapering separating-chamber having an imperforate peripheral wall in which the whirling body of air forms a vortex, and in which the air moves from the periphery toward the axis of the vortex as it becomes freed fromthe solid matter, said chamber having at its large end a tangential inlet for the dust-laden air, and a dischargeaperture for the purified air opening into the atmosphere, and provided with a tubular guard projecting into the separatingchamber, and at its small end a discharge opening for the separated dust, substantially as set forth.

Witness my hand this 5th day of June, 1880.
